Actuator

An actuator comprising:

• a flexible electrode having flexibility;
• a first base electrode disposed to face the flexible electrode on a first axis and provided with a first insulating layer on an opposite face facing the flexible electrode;
• a second base electrode disposed to face the flexible electrode on a second axis crossing the first axis at an origin located at the center of the flexible electrode and provided with a second insulating layer on an opposite face facing the flexible electrode;
• and
• an output member adapted to be displaced according to deformation of the flexible electrode and output work to an outside,
• wherein:
• a first space is formed between the first insulating layer and the flexible electrode, in which the flexible electrode deforms toward the first insulating layer by a voltage applied across the first base electrode and the flexible electrode, and
• a second space is formed between the second insulating layer and the flexible electrode, in which the flexible electrode deforms toward the second insulating layer by a voltage applied across the second base electrode and the flexible electrode.
